Map: Bike accident

PHOENIX -- Police say a girl, either 11 or 12 years old, remains in critical condition after being hit by two cars Wednesday night.

This was its own kind of Halloween nightmare. A father and daughter bike trip through Phoenix on a busy night ended in a horrifying crash. It happened during rush hour near 20th Avenue and Indian School Road.

"Witnesses are indicating that the father and daughter were on the south side of the street and crossing north," said Sgt. Trent Crump with the Phoenix Police Department.

Those same witnesses told officers the pair made it across eastbound Indian School to the median in the middle. Then the girl prepared to cross the westbound lanes.

"We understand that the child was in the lead, and the child was hit by a car heading westbound," Crump said. "We believe she was knocked off the bike, and at that point was knocked off into another vehicle that was in the curb lane, ultimately being struck by a second vehicle."

The mangled bikes and single pink sandal were all that remained. Police said this crosswalk does not have a stoplight, but it does have crosswalks and plenty of signs warning drivers to look out for pedestrians.

Officers said the drivers of the two cars involved stopped immediately after the incident and have been cooperating with the investigation ever since. Detectives are still looking into whether the sun was a factor, if the girl darted out, or if the drivers simply didn't see her.

"Regardless of what they determine as being at fault here, we've got to remember before you enter the roadway to make sure the traffic has yielded to you," Crump said.

The girl is still in critical condition at Phoenix Children's Hospital.
